The optical and non-contact measurement capabilities in the centre allow us to perform
dynamic and static measurements on a wide variety of test objects encompassing very
light structures, small and large structures as well as fluids. Combined with our modal
testing and analysis capabilities, we can automate tests using our scanning laser
vibrometers while our photogrammetry capabilities allow us to perform 3D full field
strain and motion measurements. We also have four IDT Vision NX 8-S2 high speed
cameras which allow us to do motion analysis at high frame rates.
